Unit, which shortens the length of the main transmission chain of the machine tool to zero, realizes the "zero transmission" of the machine tool, and has the advantages of compact structure, high mechanical efficiency, high rotation speed, high rotation accuracy, low noise and small vibration, etc. Modern CNC machine tools have been used more and more widely.
轴承座是电主轴中一个十分关键的精密零件，内装轴承和主轴，其制造精度直接影响电主轴的使用寿命，轴承座尺寸精度要求高，内孔的尺寸精度一般要求在0.005mm以内，形位公差要求也高，内孔的圆柱度一般要求在0.002mm以内，内孔和外圆的同轴度及端面跳动一般要求在0.002mm以内，轴承座的精加工一般采用精密数控万能磨床磨削内外圆及其端面，由于轴承座的特殊结构，内孔和外圆磨削一般需要分两次装夹，第二次装夹以前面的已经磨削的面为基准校调，时间长且会产生累积测量误差，生产效率低，质量得不到保证。另外，轴承座在使用过程中容易发生变形，导致电主轴精度不稳定，使用寿命较短。The bearing seat is a very critical precision part in the electric spindle. It contains bearings and the main shaft. Its manufacturing accuracy directly affects the service life of the electric spindle. The dimensional accuracy of the bearing seat is high, and the dimensional accuracy of the inner hole is generally required to be within 0.005mm. The tolerance requirements are also high. The cylindricity of the inner hole is generally required to be within 0.002mm, the coaxiality of the inner hole and the outer circle and the runout of the end face are generally required to be within 0.002mm. The precision machining of the bearing seat is generally used for grinding the inside and outside of the bearing seat. Due to the special structure of the bearing seat, the inner hole and the outer circle grinding generally need to be clamped twice, and the second clamping is based on the previous ground surface, which takes a long time and will cause Accumulated measurement errors, low production efficiency, and unguaranteed quality. In addition, the bearing seat is prone to deformation during use, resulting in unstable precision of the electric spindle and a short service life.
